R-27R/ER Homing Question

[RadishRabbit]

When 27R/ER homes on enemy aircraft, the circular target designator on the HUD starts flashing.

 

My question is, when that circular target designator stops flashing (but target still locked), does it imply that misslie homing fails, regardless of the relative positions of the missle and target?

 

Thanks

When the circle is flashing, IIRC, the radar has lost lock and is attempting to reaquire. The missile may potentnially not be able to guide at this point, but if lock is re-established there's a chance that the target is sitll where the missile was looking when lock was lost (more or less) and it can reacquire.

 

However, the system might switch from radar to IRST automatically if radar lock is not re-established, in which case your missile should fail to guide.

i didn't mean the flashing of big/small circles

 

i meant when you are guiding the missile, the big circle flashes on its own, if u've noticed.

When you see circle to start flashing during lock, enemy target is turning on ECM and you have to relock him after sec.

As long as the circle is flashing the missile is receiving path corrections from your radar (so the missile is flying nose cold at that moment). When the circle stops flashing you don't need to have the target locked with your radar anymore, at that moment the missile turns it's own radar seeker, and it's going for (hopefully for you) a kill :D

Yes, you do need to have it locked if it's not an R-77

With the -27R/ER, the flashing circle means that you have a target locked and you are tracking with a missile in the air. When the circle stops flashing, the target has maneuvered to place himself outside of your missile's ability to catch him. You are still tracking but he has turned sufficiently away that your missile has now fallen outside of launch parameters. In essence, he is now "out of range" as far as your missiles are concerned. You will not be able to launch a 2nd missile until you either maneuver to catch him again or select a missile with the "legs" to catch him.

Is it me or are the different accounts given here contradictory? I must confess I'm lost.

I might be wrong, it's been a while since I've done BVR in the russian birds ;)

Everybody is right : you have :

- the "basic" flashing indicating, as IronHand put it nicely, that your missile is guided and in progress. And it starts flashing as soon as a missile is fired :)

- the "advanced" flashing, where the circle flashes by changing its size ie shrinks and grows :) That means that the radar has lost the lost and you need to do something very fast if you want to regain it and not loose a missile :)

To get back to the initial post, IronHand gave you the answer, RadishRabbit :)

Thanks!

So, when you have a lock and missile in the air homing, the circle indeed flashes. But is it the case that when the circle stops flashing and remains a steady circle, you still have a lock but it shows that your missile is not homing anymore (went for some chaff) and your shot is a miss? This is relevant information.

the HUD info will only show if radar is still tracking and has a lock... not if the missile is still tracking...
